Definitions
- the present invention relates to an apparatus for pulling out a pattern plate from a carrier plate that is dropped into and fitted with a pattern plate for forming a sandstone mold and conveyed on a mouthpiece conveyor.
- the present invention has been made in view of the above problems, and it is possible to simultaneously pull out two pattern plates from a carrier plate that holds two pattern plates, and it is also possible to pull out only one pattern plate. It is an object of the present invention to provide a pattern plate pulling-up device which can be pulled out safely and securely in a short time.
- an apparatus of the present invention is an apparatus for pulling out a pattern plate held in a carrier plate and conveyed on a conveyance path from a carrier plate, and having a biston rod extending upward. It has a first lifting / lowering cylinder arranged and fixed below the transport path, a mounting table attached to the tip of the first lifting / lowering cylinder biston rod, and a biston rod extending upward and separated from the mounting table. And a second and a third lifting cylinder having a plurality of pull-up pins erected on the mounting plate and mounted on the tip of the biston rod.
- the lifting pin By raising the piston rod of the first lifting / lowering cylinder, the lifting pin is moved toward the carrier plate that is located above the device and holds one pattern plate, and is passed through the through hole formed in the bottom to carry the carrier plate.
- the second or third lifting cylinder can be pushed up to the carrier plate that holds the two pattern plates by raising the piston rod of the second or third lifting cylinder. It is also possible to move the lifting pin and push up one pattern plate through the through hole formed in the bottom of the carrier plate.
- FIG. 1 is a sectional side view showing an embodiment of the device of the present invention.
- FIG. 2 is a diagram showing an arrow A—A in FIG.
- FIG. 3 is a sectional side view similar to FIG. 1, showing a state where a pattern plate is pulled out.
- FIG. 4 is a cross-sectional side view similar to FIG. 1, showing a state where one of two pattern blades is pulled out.
- a roller conveyor 3 is provided as a transport path on a frame 20 fixed to the floor.
- Carrier plate 2 that holds pattern plate 1 inside stops at transport path 3.
- Eight through holes 4, 4 A are provided at the bottom of the carrier plate 2.
- the carrier plate 2 receives a green frame thereon to form a molding space filled with natural sand. Therefore, the pattern plate 1 is firmly fitted to the carrier plate 2 so as not to move.
- Frame 20 is composed of two evening rooms 21 and 21 and suspended from these tie beams. Included are four uprights 22,22. A horizontal frame member 6 is fixed to an end of the vertical member 22.
- the first lifting cylinder 5 is provided on the frame member 6, and the piston rod 5A of the first lifting cylinder 5 is provided so as to extend upward.
- a mounting table 7 is fixed horizontally.
- Two spaced-apart second and third lifting cylinders 8, 8A are attached to the table 7 at positions on both sides of the first lifting cylinder (FIG. 1).
- the 8 and 8 A biston rods 9 and 9 A of the second and third lifting cylinders are provided so as to extend upward.
- Attachment plates 10, 10A are fixed horizontally to the tip of piston rods 9, 9A of the second and third lifting cylinders 8, 8A.
- pull-up pins 11 and 11 A extending upward are provided. These eight pull-out pins 11 and 11 A correspond to the through holes 4 and 4 A provided at the bottom of the carrier plate 2.
- the second lifting cylinder 8 includes two guide rods 12 extending downward from the mounting table 7 and engaging with the frame member 6, and the third lifting cylinder 8A extends downward from the mounting table 7. It has two guide rods 12A and 12A that engage with the frame member 6. These guide rods 12 and 12 A prevent the mounting table 7 from rotating when ascending and descending and guide its vertical movement.
- the second lifting cylinder 8 has a plurality of guide rods 13 (only one is drawn in FIG. 1) extending upward from the mounting plate 10 and engaging with the frame 20, and the third lifting cylinder 8A is A plurality of guide rods 13A (only one is illustrated in FIG. 1) are provided to extend upward from the mounting plate 1OA and engage with the frame 20. These guide rods 13, 13A prevent the mounting plates 10, 10A from rotating when ascending and descending, and guide their vertical movement.
- the third lifting cylinder 8A can be operated.
